cd7 car-t cells for patients with r/r cd7+ nk/t cell lymphoma,t-lymphoblastic lymphoma and acute lymphocytic leukemia

Conditions: T-lymphoblastic Lymphoma; NK/T Cell Lymphoma; Acute Lymphocytic Leukemia

Summary: this study is designed to explore the safety and efficacy of cd7 car-t cells for patients with relapse/refractory cd7+ nk/t cell lymphoma ,t-lymphoblastic lymphoma and acute lymphocytic leukemia. and to evaluate the pharmacokinetics of cd7 car-t cells in patients.
